DRILL-FEED.

Application filed June 3,

To all whom it may concern:

Be it known that I, VILLIAM HARVEY GREENE, a citizen of the UnitedStates, residing at Ann Arbor, in the county of Vashtenaw and State ofMichigan, have invented a new and useful Drill-Feed, of which thefollowing is a specification.

My invention relates to attachments hand and breast drills.

The object of the invention is to provide a device whereby the materialto be acted upon by the drill may be held against the same and wherebythe attachment may be adjusted to accommodate material of differingthicknesses.

Broadly speakin the invent-ion comprises slidably connected rods, one ofwhich is adapted to be detachably secured to the stock of the drill, theother of which is provided with an anvil to receive the work. The handleis pivoted to the outer end of the rod which is attached to the stockand has a connection with the clutch mounted upon the other rod, wherebythe downward motion of the lever will cause the anvil to advance toward'the drill,

Vith the foregoing and other objects in view, the invention consists ofcertain novel features of construction, combination and for arrangementof parts, as will be more fully described and particularly pointed outin the appended claims.

In the drawings, Figure 1 is a side elevation of the drill showing theattachment, partly in section, applied thereto; Fig. 2 is a transverse.section on the line 2-2 of Fig. 1.

Referring more especially to the drawings, A and B represent the tworods, the outer end of the latter one being provided with the curvedanvil b and the outer end of the former one being turned at right anglesand having universally connected thereto a coupling device F carrying aset screw in its outer end for engaging the shank of the drill. The rodsA and B are connected together by yoke members 1 and 2, the former beingcarried at the outer end of the rod A and the latter being carried atthe inner end of the rod B, and surrounding the rod A.

Pivoted to the outer end of the rod and between the legs of the yokemember 1, is a lever E which is connected by a link D Specification ofLetters Patent.

I to a clutchmember C. This clutch member C surrounds the rod B abovethe sleeve 1 and when tilted downwardly at its outer end, binds upon therod at the points 0, d and thus causes the rod B to move with the clutchmember. Therefore, if the lever E is depressed, it will pull down uponthe clutch member C and cause it to bind upon the rod and pull said roddownwardly so that the yoke member 2 slides upon the rod A and the anvilb is brought closer to the drill. By holding onto the lever E with onehand and placing the forefinger through the loop in the outer end of theclutch member C and pressing downwardly thereon, the operator can workthe lever E up and down, which will produce the following result. Uponthe downward movement of the lever E, the clutch member will grasp therod B and carry it along with it. Upon the upward movement of the leverE, still main taining the downward pressure on the loop end of theclutch, the clutch member will slide upon the rod B and thus positionitself to secure a fresh grip. The reverse operation may be carried outby grasping the lever E in the same manner and exerting an upwardpressure upon the outer end of the clutch member C. Now, when the leverE is moved upwardly, the clutch member will grasp the rod and move italong with it and when the lever is moved downwardly the clutch memberwill slide idly over the rod B, so as to get a fresh grip. Continuedmovement in either direction will eventually move the rod to its limit.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention, as defined in theappended claims.

I claim:

1. A device of the class described, comprising a pair of slidablyconnected members, a drill connecting member hinged to one of saidmembers, an anvil carried by the other member, and means to draw theanvil toward the connecting member.

2. A device of the class described, c0mprising a pair of slidablyconnected members, a drill connecting member having universal connectionwith one of the members,

5 an anvil carried by the other member, a clutch slidably mounted on oneof said members, and means pivoted to the other of said members andhaving connection with the clutch to draw the anvil toward the drillconnecting member.
